Securely using VNC over SSH
 

If I do THIS in one terminal window

> ssh -L 5900:localhost:5900 -l van <target computer>

And THIS in a separate term window

> vncviewer <target computer>:0

I have a secure VNC connection to the desktop of my target computer (I already have ssh keys setup so there is no password prompt ssh-ing to the target)

But if I make one shell script with both commands

#!/bin/sh
ssh -L 5900:localhost:5900 -l van <target computer> &
vncviewer 127.0.0.1:0


And execute it, I get two errors
"Pseudo-terminal will not be allocated because stdin is not a terminal"

and a VNC error

"unable to connect to host. Connection refused (111)"


How should I be scripting this so I can have one shellscript establish the ssh port forward and then run my vncviewer over it?


- Van

ssh -f -L 5901:localhost:5900 targetcomputer sleep 20
vncviewer -owncmap localhost:1
